Ultrasonic tomographic reconstruction considering wood anisotropy

[Lien vers la fiche source] We proposed an approach to solve the inverse problem for tree imaging, using a method based on ultrasound travel-time tomography and adapted to the anisotropy of wood material. The proposed inversion procedure was developed between 2015-2018. The method considers the dependency of the wave velocity on the angle of propagation and the wood elastic constants, as described by the Christoffel equation. This dependency leads to curved trajectories (or rays), that are followed by the wave from the source to the receivers, affecting the time-of-flight (TOF) measurements. A first inversion is performed considering an hypothesis of straight-line rays, using an algebraic reconstruction algorithm (SIRT), adapting the matrix formulation to obtain the slowness for every pixel as a polynomial approximation of the Christoffel equation. Then, the obtained set of slowness functions are used to perform the direct (or forward) problem, simulating the wave propagation using a raytracing approach. This simulation allows to estimate the curved trajectories and synthetic TOF values, that are then compared to the experimental measurements. This process is repeated iteratively until convergence. From the final iteration, the polynomial approximations of the Christoffel equations for each pixel are used to obtain the elastic constants via a non-linear regression. Finally, the parametric image is presented. The data folder contains the time-of-flight measurements (in seconds) and the sensors positions (in meters) from an experimental setting using pine samples. A photography of the cross-section is included. TOF values are organized as a matrix (sinogram), where columns correspond to each source, and receivers to each row. Sensors positions are presented as a column vector, specifying the [X,Y] coordinates. Three different configurations were tested: (1) a healthy case, (2) a centered defect case and (3) an off-centered defect case. Defects were simulated by drilling a circular hole of diameter 7.6 cm. The forward folder contains the code to perform the raytracing simulation (direct problem), used in the iterative inversion schema. The main file is rayPix‧m, that performs the raytracing. The inverse folder contains the code to perform the image reconstruction (inverse problem). The main file is optimFinal‧m, where the iterative schema was implemented. To perform an inversion, the directives are in mainInv‧m
Informal waste collectors and aggregators space and activities in Vinh city, Vietnam, COMPOSE project (2019-2021)

[Lien vers la fiche source] The system of informal waste collectors and aggregators in Vinh city (Vietnam) was surveyed in the framework of the COMPOSE project (2019-2021). The social survey based on questionnaire was carried out in the entire area of Vinh City, Nghe An province to identify the location of the aggregator warehouse participating to the informal waste collection and recycling in the city. Then, the collectors and aggregators were interviewed individually to collect information on the space, architectural characteristic of the warehouse, the neighborhood, the hours of operation, the type of materials collected and on the owners of the warehouse (hometown, the reasons for choosing the job). These quantitative surveys were conducted in August 2019 and June 2020. Data anonymization was performed by removing identifiers, generalization (grouping precise values into less precise and large categories) and finally by aggregating individual records, producing descriptive statistics (frequencies).

Fasta files for InpactorDB: A Plant classified lineage-level LTR retrotransposon reference library for free-alignment methods based on Machine Learning

[Lien vers la fiche source] Here, we present InpactorDB a semi-curated dataset composed of 130,511 elements from 195 plant genomes belonging to 108 plant species, classified down to the lineage level. This dataset has been used to train two deep neural networks (one fully connected and one convolutional) for fast classification of elements. Used in lineage-level classification approaches, we obtain a score above 98% of F1-score, precision and recall. In order to classify elements of the ‘LTR_STRUC' and ‘EDTA' datasets, we used the methodology proposed by [Inpactor], which uses homology-based strategy with known coding domains belonging to LTR-RTs. We utilized the [RexDB] domain library as reference. LTR-RTs were classified into superfamilies, Gypsy (RLG) or Copia (RLC) and sub-classified into lineages according to the similarities of five different amino acid reference domains (GAG, AP, RT, RNAseH, and INT domains). In addition, we applied filters to keep only intact elements: 1. to remove predicted elements with domains from two different superfamilies (i.e. Gypsy and Copia), 2. or elements with domains belonging to two or more different lineages, 3. to remove elements with lengths different than those reported by [Gypsy Database (GyDB)] with a tolerance of 20%, 4. to delete incomplete elements which has less than three identified domains, and 5. to remove elements with insertions of TE class II (reported in [Repbase]). The final non-redundant version of InpactorDB consists of 67,305 LTR retrotransposons. Both redundant and non-redundant versions of InpactorDB are available in Fasta format in which sequences have identifiers with the following general Identification code: >Superfamily-Lineage-plant_family-specie-source-length-ID where Superfamily can is either RLC (for Copia) or RLG (for Gypsy), Lineage/family following the RexDB nomenclature, source (can be Repbase, RepetDB, PGSB, LTR_STRUC or EDTA datasets), length, and ID, is a unique number which identify each element inside the InpactorDB.
